Intel SDE not working (assertion_failed: res=TRUE)

Niko1154 — Mon, 09 Dec 2024 19:04:05 GMT

Hello,

I've been trying to get this Intel SDE to work for quite some time now, and just as I fixed one problem another popped up.

E: [tid:7676] SYSCALL_INSPECTOR: NTDLL module is rebased
A: C:\tmp_proj\sde_jenkins\workspace\pypl-sde-nightly-master\GitSDE-master-9.23.0-39-g1c4e8ff06\pin\Source\pin\base_w\ipc_server_windows.cpp: StartServer: 1283: assertion failed: res == TRUE

NO STACK TRACE AVAILABLE

This is the error it gives me when I try to run the SDE even with a simple command such as : sde.exe -- cmd.exe

After this error I can see the task in task manager but it is suspended and doesn't do anything no matter how long I wait.

I don't know what else to try so I hope someone here can help me.

This looks like an old version of Intel SDE.

Please try using the latest version.

Hi there,
The fresh-downloaded SDE version returns the same error with Windows 11 with latest patches.

Edition Windows 11 Pro
Version 25H2
Installed on ‎2/‎23/‎2025
OS build 26200.7462
Experience Windows Feature Experience Pack 1000.26100.275.0

Could you please test it and confirm?
Or provide please steps how to run SDE on the latest Win 11?

Hi Ady,

I've just tried latest version 10.5.0 from Intel site.
It still doesn't work on Windows 11.

Now it says:
Launcher error: OS_INFO: Unsupported OS version 6.1

Hi,

Are you sure that you are running on Win11?

OS Version 6.1 is either Windows Server 2008 R2 or Windows 7 - both are indeed not supported by Intel SDE.

Ady.

Thank you for noticing it. It made me dig a little deeper.
Looks like after my latest experiment I left console in compatibility mode.
After resetting settings SDE works just fine.
All target platforms ran successfully.

Thank you for your help
